APRON FOR COKE-OVEN DOORS.

Application filed February? T 0 aZZ whom it may concern.

Be it known that we, Lit-MAN E. DOTY and F RANKLIN H, SMITH, citizens of the United States, and residents, respectively, of Elyria, in the county of Lorain and State of Ohio, and Brentwood Borough, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Apron for Coke- Oven Doors, of which the following is a specification.

This invention relates to coke oven doors, and more particularly to apron plates for coke oven doors, and has for one of its objects the provision of a permanent plate of this class that will bridge the space between the coke oven and the coke guide.

Another object is to provide a device of this class that will clear the coke guide, thereby allowing the coke guide to be freely moved at all times.

Another object is to provide an apron plate that will be rigidly secured below the oven floor line, thereby eliminating the possibility of the coke or pusher ram catching on the plate, buckling, or breaking the same.

Heretofore it has been the practice to use a movable apron plate attached to the coke guide, which was moved along the inspection walk to the oven to be drawn, and said plate was dropped down between the buckstays of the oven to bridge the space between the oven floor and coke guide. Such apron plate has proved very unsatisfactory since the pusher ram or coke often caught on the plate and buckled it, or at times the operator would move the coke guide without first lifting the apron plate and bend it. Another disadvantage of this style of apron plate was that if the coke stuck for any reason, when partly into the guide, it was impossible to move the guide since the apron plate was locked in position between the buckstays.

All of the above disadvantages are overcome by the apron plate of this invention, which is permanently secured in position between the buckstays of the oven and leaves the coke guide free to move when desired.

Referring to the drawings, Figure 1 is a horizontal sectional plan of a portion of Specification of Letters Patent.

Figure 2 is a front side elevation of an apron plate applied to an oven.

igure 3 is a cross sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a sectional plan on the line l4 of Figure 2.

Referring particularly to the drawings, the apron plate is designated generally by the letter A, and is adapted primarily for use in connection with coke ovens of the byproduct type, which comprise a plurality or battery of narrow coking chambers or ovens arranged side by side, having a floor 2 and side walls 3. The ends of the ovens are open forming doorways, and suitable inspection walks or platforms 4 are arranged parallel with the ends of the ovens.

A pusher ram of well known construction is adapted to be entered into the oven, through the doorway at one end, and push the coke out of the other doorway at the other or exit end.

The usual channel-shaped buckstays 6 and 7 are arranged vertically on the end of the ovens parallel with and on each side of the doorways.

A coke guide 8 is adapted to be moved along the inspection walk 4 to receive the coke as it is pushed from the oven and guide it over the walk into suitable cars or the like. The guide 8 must necessarily clear the buckstays 6 and 7 and, therefore, leaves an intervening space between the oven doorway and guide. The apron plate A of this invention is adapted to bridge the space between the coke guide 8 and the oven doorway.

The apron plate A, comprises a casting having a smooth top face 9, side walls 10, end walls 11, end retaining flanges 12 and suitable strengthening ribs 13. The apron plate A is adapted to have its retaining flanges extend within the channeled buckstays and to be supported on a suitable channel support 14; arranged between the buck stays 6 and 7 and supported on angle-shaped brackets 15, riveted or otherwise secured to the buckstays.

The channel support 14 is secured to the angle-shaped brackets 15 by bolts 16, which pass through elongated apertures in the channel and brackets so as to allow for expansion due to the heating and cooling of the apparatus.

The retaining flanges 13 of the apron plate are provided with apertures 17 of sufiicient size to clear the bolts 16 holding the channel 14 in position.

The apron plate A is held in position by bolts 19 which pass through elongated alined apertures in the flanges 18, channel support 14 and brackets 15, thus allowing for movement of the plate, due to expansion and contraction when heated and cooled.

Suitable fillers or liners 20 are mounted around the bolts 19 between the bottom face of the flanges 13 and the top face of the channel support 14 to adjust the apron plate A, to proper height with relation to the coke guide 8 so that the plate A and guide 8 will form a practically continuous smooth surface over which the coke may be pushed. I

While we have shown and described one particular embodiment of our invention it will be understood that we do not wish to be limited to such construction since it is only illustrative, and various minor changes in design and construction may be made without departing from the spirit of the invention as defined in the appended claims.

We claim 1. The combination with a coke oven having an exit doorway, and buckstays along the sides of said doorway, of a coke guide adapted to travel along the front of said oven and to clear said buckstays, a supporting member secured to said buckstays, and an apron plate mounted on said supporting member between said buckstays adapted to bridge the space between said oven and said coke guide, and bolts passing through elongated slots in said apron plate and said supporting member for securing said apron plate in position.

2. The combination with a coke oven having an exit doorway, and buckstays along the sides of said doorway, of a coke guide adapted to travel along the front of said oven and to clear said buckstays, and an apron plate arranged between said buckstays adapted to bridge the space between said oven and said coke guide, said apron plate being supported on a channel-shaped supporting member secured to said buckstays, and bolts passing through elongated slots in said apron plate and said channel supporting member for securing said apron plate in position.

3. The combination with a coke oven having an exit doorway, buckstays along the sides of said doorway, of a coke guide adapt ed to travel along the front of said oven and to clear said buckstays, and an apron plate arranged between said buckstays adapted to bridge the space between said oven and said coke guide, said apron plate being supported on a channel-shaped supporting member securedto suitable angle brackets on said buckstays, and bolts passing through elongated slots in said apron plate and said channel supporting member for securing said apron plate in position.

In testimony whereof, we have hereunto signed our names.
